Quick Answer
To set up 12mm clamping hex hubs on your RC axle, clean the stub shaft, slide the hex on, align the flat, and tighten the clamping screw to spec. This prevents pin breakage and wheel wobble.
Why Clamping Hex Beats Pin-Style Hubs
Clamping hex hubs use a screw to pinch the hub onto the axle stub shaft, eliminating the need for a drive pin. This design reduces stress on the pin and prevents the slop that often develops with pin-style hubs.
The Vanquish Products 12mm clamping hex is machined to tighter tolerances, so it fits the stub shaft more precisely. This means less play between the hub and axle, which translates to more consistent power delivery and less wheel wobble at speed.
What You Need Before You Start
Gather a 2mm hex driver (or the correct size for your screws), a clean cloth, and optionally threadlocker. The Vanquish clamping hex kit includes two hubs and two 2-56 SHCS screws, so you have everything needed for one axle.
If your axle has a pin, remove it first. Clamping hex hubs replace the pin system, so the pin is not needed and can interfere with the hub's fit.
Step-by-Step Installation
- Prep the Stub Shaft: Wipe the axle stub shaft clean and inspect for burrs or damage. Remove any existing pin or hardware. A clean shaft ensures the hex sits flush and prevents wobble.
- Slide the Hex On: Orient the hex so the flat side aligns with the shaft's flat (if present) and slide it fully onto the stub shaft. Ensure it seats completely against the axle. Check that the hex is flush; a gap indicates misalignment.
- Tighten the Clamping Screw: Insert the 2-56 SHCS screw and tighten it gradually, alternating if there are two screws. Use a hex driver and snug it firmly, but avoid over-torquing to prevent stripping. If the wheel still wobbles, re-check the screw tightness and hub seating.
Product Facts
-
12mm Clamping Hex: The Vanquish Products 12mm clamping hex is aluminum and uses a clamping design to help alleviate pin breakage. This means you get a more secure wheel mount that reduces the chance of stripping or breaking drive pins, especially on rough trails.
